Why move the sound head during ultrasound therapy?

• A. Potentially cause damage tissue
• B. Increase energy delivery
• C. Reduce treatment time
• D. Improve patient comfort

Answer: (A)

Moving the sound head is done to prevent tissue damage from hotspots. Therapeutic ultrasound delivers energy that raises tissue temperature; if the head stays in one spot, energy concentrates in a small area, potentially causing overheating and injury. Keeping the head in motion distributes energy more evenly across the treatment area, reducing the risk of local tissue damage and providing a safer, more uniform therapeutic effect. While movement can also improve comfort to some extent, safety from overheating is the primary reason.
